Depends on how up-to-date your install image is. If you downloaded the ISO 6 months ago, chances are, the build you downloaded is out of date (doubly so if it’s Arch). Most installers have an online option that will download the updates and install the newest version, but if you don’t have access to the internet, then all you have is the data included in the ISO that you got 6 months ago.
You can also change it to literally anything you want.
